I would like to know what experiences others have had with Koehnen bees. This is my second year with Koehnen queens and packages and while others are getting honey crops with their bees, my Koehnen bees fail to build up and then there is no honey. Last years queens began to fail into laying workers beginning in the early summer and now I have lost most of the colonies that didn't get a queen cell emerged (this spring) and mated. I wish I could rule out disease but I can't. There are no obvious symptoms of anything and mite counts have been below 2% all season. No visible brood diseases, low mite counts, and the bees seem normal other than they don't build up.
My understanding is that Koehnen doesn't produce any honey and is strictly a producer of bees and not a crop. Is it possible that their bee are not very good at making honey. I switched from Buckfast to Koehnen bees because my Buckfasts were likely africanized and were extremely aggressive and Koehnen was the largest producer in California of packages and queens so I gave them a try. Their queens are very gentle, which was refreshing, but since using them, I have not seen any honey. Not only is there no honey crop (six different bee yards), but I won't have enough bees going into almonds this year to break even.
Has anyone else had similar experiences with Koehnen bees? Any thoughts on the lack of build up?
